HENRY SCHREYER, OF TOLEDO, OHIO.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 492,842, dated March 7, 1893.

Application filed September 16. 1892. Serial No. 446,097. (No model.)

To all whom it may concern:

Be it known that I, HENRY SCHREYER, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio,have invented certain new and useful Improvements in Oar-Couplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in automatic car couplers and it consists in the peculiar construction and arrangement of parts as will be hereinafter fully pointed out and claimed.

In the accompanying drawings-Figure 1 is a perspective view of a coupler constructed in accordance with my invention showing the same open. Fig. 2 is a vertical longitudinal sectional View through the coupler showing the parts closed or locked. Fig. 3 is a vertical sectional view on the line 50-00 of Fig. 2. Figs. 4 and 5 are detail views of the retaining block. Fig. 6 is a detail plan view of the rear end of the movable jaw and the retaining block.

Like letters of reference denote corresponding parts in the several figures of the drawings, referring to which- A designates the draw head and A the draw bar which may be of any suitable size and material. The draw head A is provided at one side with parallel overhanging lugs B between which is fitted the reduced tailpiece of the movable jaw O and said jaw is held in place by a pivot pin 0. On the lower sur face of the tail piece of the jaw G is formed a cam or incline c which rests against or on an oppositely arranged incline 0 formed on the upper surface of the lower lug B of the drawhead A. The floor or bottom of the drawhead is inclined downwardly from its inner to its outer end, as shown in Fig. 2, and on said inclined surface is arranged a retaining block D which is provided in one side, near its rear end,with a recess designed and adapted to receive therear end of the tail piece of the movable jaw O of the coupler. On the opposite side of the block D is formed an integral lug E which extends into a way formed in the The upper surface of the lug E is inclined downwardly from its rear to its forward side and on'said inclined top rests, when the movable jaw is'in the position shown in Fig. 1, the lower end of a vertically-movable locking slide F. The slide F extends through a suitable aperture in the top of the drawhead and said slide is provided in its outer face'with a projecting stud or pin G which works in a vertical slot formed in the side of the drawhead. The upper end of the locking slide Fis shaped so as to be conveniently grasped by hand and is provided near its upperend with an opening or aperture through which a lifting bar or any suitable implement can be passed when it is desired to raise said slide without passing between the adjacent ends of two cars;

In the slide F is also formed a pin passage or aperture designed to receive a pin G by means of which said slide can be held slightly elevated.

The forward portion of the retaining block on the same side as the lug E is cut away and in such reduced portion is fitted an adjusting plate H, substantially triangular in shape and in said plate is formed an inclined slot I into which a headed pin K rigidly attached to the block D extends so that the block D r and plate H can be moved longitudinally one on the other. As shown in the drawings, the plate H projects or extends above the block D at its its forward end when the movable jaw O is open and as said plate is forced rearwardly in the drawhead it operates to move the retaining block both upwardy and rearwardly.

In the forward end of the movable jaw O is formed a recess or slot adapted to receive one end of a coupling link in case it is desired to employ my improved coupler with the ordinary pin and link coupling.

The operation of my invention may be briefly stated as follows:VVhen two cars, provided with my improved coupling come together, the movable jaw of one coupler enters thespace in the other coupler between the fixed and movable jaw and comes in contact with theforward end of the adjusting plate H. The adjusting plate is forced rearwardly along the inclined bottom of the drawhead and by such rearward movement the retaining block D is also forced rearwardly and upwardly and the swinging jaw 0 caused to swing or turn inwardly on its pivot. The block D is pushed. rearwardly in the draw head sufficiently far to enable the lug E carried thereby to pass from under the verticallymovable locking slide F which falls, by gravity, in advance of the lug E and holds the block D and jaw O firmly in place. To uncouple the cars it is only necessary to raise the slide F far enough to clear the upper edge of the lug E when the movable jaw C will antomatically swing open and the block D and pl ateH be moved into the positions shown in Fig. The forward motion of the movable .jaw is aided by the oppositely arranged invclines o', c.

When it is desired to employ my improved coupler in connection with an ordinary pin and link coupling the pin G is withdrawn from the aperture in the locking slide to permit said slide to fall and lock the movable aw firmly in place. The coupling link can then be inserted in the recess provided for that purpose in the forward end of the movable pin and held in place by a coupling pin of ordinary form. It will be noticed that the pin G is connected to the locking slide by a short chain.

I am aware that changes in the form and proportion of parts and details of construction of the devices herein shown and described as an embodiment of my invention can be made without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as fairly fall within the scope of the same.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a car coupler, the combination of a drawhead, a movable jaw pivotally connected to the drawhead, a retaining. block arranged in the drawhead and engaging with the rear end of the movable jaw, an adjusting plate carried by the retaining block, and a vertically movable slide adapted to hold said block firmly in place, substantially'as described.

2. In a car coupler, the combination of a drawhead, a movable jaw, a retaining block engaging with the rear end of the movable.

jaw and provided on one face with an integral lug, a vertically moving locking slide and an adjusting plate carried by the retain ing block and adapted to move the same to bring the lug thereon in rear of the locking slide, substantially as described.

3. In a car coupler, the combination of a drawhead, a movable jaw, a retaining block engaging with the rear end of the movable jaw and provided ,on one face with an integral lug, a plate carried by said block and adapt-ed to move the same rearwardly and upwardly and a vertically movable locking slide provided with a-stud or pin which works in a vertical slot in the side of the drawhead, substantially as described.

4. In a car coupler, the combination of a drawhead provided with an inclined bottom, a movable jaw, a retaining block arranged within the drawhead and engaging with the rear end of the movable jaw, a vertically movable locking slide and an adjusting plate connected to the retaining block by a pin and slot connection and adapted to move said block in the drawhead to bring a lug thereon in rear of the locking slide, substantially as described.

5. In a car coupler, the combination witha drawhead and movable jaw, of a retaining block engaging with the rear end of the movable jaw, a locking slide and a longitudinally movable adjusting plate adapted to move the retaining block rearwardly and upwardly by means of coacting inclines arranged between said block and plate, substantially as described.

In testimony whereof Iaffix my signature in presence of two witnesses.

HENRY SOHREYER.
